Correct backfocal distance with Tak flattener and longer Lum subs (but only 1 minute each RGB (!) as it was a late target for the night) - improved result over last year's attempt. Now picking up outer dust areas, even from my orange/red-level light polluted backyard (to that end, was a challenge reducing LP gradient).
